How does Chapter 22 detail the method for seeing the 'crescent moon' on Sai Baba's big toe?

Chapter 22 provides a specific description of how devotees could witness a divine vision at Sai Baba's feet. The text explains that when Baba sat with his right foot over his left knee, the nail of his right big toe would shine like the crescent moon of the second day. To see this, a 'wise one' would instruct a devotee to use the index and middle fingers of their left hand to create a gap. By fixing their gaze through this gap towards the big toe, the small 'crescent' would become clearly visible. This practice is compared to the longing people have to see the moon after the dark night of the New Moon, fulfilling the devotees' spiritual curiosity as mentioned in the chapter.
